Chemical charring and activation with potassium hydroxide (KOH) were performed to expand the pore network, increase the specific surface area, and improve the volumetric storage capacity. These materials were characterized using helium pycnometry, nitrogen adsorption, hydrogen adsorption, and scanning electron microscopy. The activation procedure resulted in a bimodal pore size distribution and a large fraction of nanopores of 7 Å pore widths that are optimal for hydrogen storage. Specific surface areas of 2595 m²/g were achieved with a crystalline volumetric storage capacity of 9.84 g/L at room temperature and 100 bar. This corresponds to an energy density around 1.18 MJ/L, which is a 28% improvement over compressed gas alone. This biowaste-derived material has the same volumetric storage capacity as the commercially available, petroleum-derived adsorbent, Maxsorb (MSC-30) produced by Kansai Coke. This demonstrates that reversible, physical adsorption of hydrogen on materials produced from biowaste may be used as a more ecologically friendly improvement for renewable energy storage.

The novelty of this approach lies in its ability to effectively remove both aqueous and gaseous pollutants, making it a versatile solution for environmental remediation. By transforming agricultural waste into a high-value material, this method not only promotes sustainability but also offers a dual-purpose adsorbent capable of addressing a broader range of contaminants than traditional adsorbents. This innovative process represents a significant advancement in both waste valorization and pollution control. With a substantial surface area of 289.82 m² g⁻¹, this carbonized biochar effectively adsorbs ofloxacin (OFX) from water and captures CO₂ in its gaseous form. Characterization of PTSB was conducted using various techniques. Batch adsorption experiments were optimized using response surface methodology (RSM), resulting in over 95 % adsorption efficiency. Isotherm and kinetics studies indicated that the adsorption process adheres to Langmuir adsorption isotherm and pseudo-second-order kinetics. Notably, a significant observation was made regarding the increase in adsorption with rising temperature. The maximum adsorption capacities (q_m) at temperatures of 303 K, 313 K, and 323 K were determined to be 96.83 mg g⁻¹, 147.56 mg g⁻¹, and 201.82 mg g⁻¹, respectively, as derived from the Langmuir adsorption isotherm. Examination of CO₂ sequestration at various temperatures demonstrated highest adsorption recorded at 273 K, reaching 49.96 mL g⁻¹. Furthermore, Q_st values for CO₂ removal were consistently below 40 kJ mol⁻¹, indicating a physisorption process. Furthermore, mathematical modeling techniques were applied to forecast the OFX breakthrough curve and assess various removal approaches. The results of this research aid in the advancement of efficient remediation techniques aimed at reducing the environmental repercussions of OFX contamination.

An indigenously developed heterogeneous catalyst was obtained that can be easily recovered and reused multiple times, proving to be cost efficient according to calculated estimates. This also reduces fuel synthesis costs owing to drastic reduction in wastewater generation. The reaction is optimized through central composite design (CCD) using five process parameters viz. reaction temperature, duration, catalyst concentration, methanol concentration and agitation speed, which resulted in maximum fuel yield of 95.77 %. Conversion of oil was optimal using methanol at 40 %w/w concentration at 60 °C reaction temperature, when the reaction occurs for a duration of 150 min with KOH-doped catalyst at 4 %w/w concentration, requiring a high agitation speed of 850 rpm.
